I have made a lot of natural ones but for a more weatherproof set up that will be placed and not moved till season is over I like a box blind. I have made a number out of 2x4's for the frame, plywood for the roof and then old carpet with jute back facing out and then simply spray painted my own camo pattern. I then cut the viewing/shooting flaps out(leaving the bottom edge attached)I attach a piece of burlap camo that will drop over the windows when sitting to reduce the chance of getting picked off but you can still see out. Iget the carpet free at carpet stores and you'd be suprised at how good some of the stuff can be that is removed. I build them in the spring and leave them to air for the summer months, they work great and are cheap.

I have pop ups as well for the easy and mobility factor. I have a couple Ameristep Doughouse that work good for the investment. though have to say my partner picked up a Double Bull Matrix and its the cadi of pop ups. Price tag suggests that though!!

Exampleof one of my carpet box blinds I built. Total cost was under 50 bucks and 2 guys can sit and/or stand comfortably.
